来源原文摘录

Browser formula racing with a PS1 / low-poly look. The webcam is the controller: hold your hands like a wheel, and we also read head pose.

摘自项目 README，照录原文，未翻译。

来源里的步骤 / 要点

1. Vite + React + Three.js — small web stack, fast to iterate on at a hackathon
2. MediaPipe Face + Hand Landmarker — geometric head pose from a few landmarks, plus both wrists
3. MobX — tracking updates every frame without re-rendering the whole app
4. Store only useful numbers — pose, wrists, wheel angle. Not the full landmark mesh
5. Driver picker — Tekken-style horizontal select of the 22 2026 F1 drivers, each with a bundled 5×5 head atlas under public/sprites/drivers/. Selected
6. Convex (optional) — anonymous lap times + leaderboard. Nickname only; no login. Without a URL the board stays on this device.
7. Driver sprite — 5×5 atlas. Nose vs eyes/mouth picks yaw/pitch, then snaps to a cell. Overlay is counter-mirrored so left/right match
8. Wheel sprite — two palm centers set position, tilt, and size so the grips sit in your hands
